Bridget Battle's last band might have been a high school choir, but the 21-year-old singer for Cincinnati's Tweens is no goody two shoes. Look no further for proof than ''Tweens,'' the punk-tinged debut from the trash-pop trio--Battle on vocals and guitar, Peyton Copes on bass and Jerri Queen on drums--that showcases a melodic, driven and exceedingly catchy sound that's anything but well behaved.
